"The geometry of the material universe at all scales, is sum of open and closed Space". -Aiya-Oba(Poet/Philosopher)
Thus; 0/x + x/x ...= 1 Where 0/x is open space, x/x is closed space, and x can be any of the infinite natural numbers. Say x = 2. 0/2 + 2/2 = 2/2. = 0 + 1 = 1 = 1 = 1 Such that; (0/x + 0/x + x/x) + (x/x + x/x + 0/x) = (x/x + x/x + x/x)
and (0/x + 0/x + x/x) + (x/x + x/x + x/x) + (x/x + x/x + 0/x)/2 ... = (x/x + x/x + x/x). Q E D The three types of geometry: Hyperbolic, Elliptic and Euclidean, are three sides or aspects of the same universal triangle(geometry). Euclidean geometry is the central and basic reference frame in Space (plane geometry). Elliptic geometry(closed space) is the opposite but equal side (pair of sides) to Hyperbolic geometry(open side) of Space- the universal isosceles triangle of All in all. In this Universal isosceles triangle, Euclidean space is the tangent, gradient and Equator(base) of Elliptic and Hyperbolic space.
"Infinite universes appear and disappear, as closed and open units of the everlasting Space (Cosmos-the Almighty One)". -Aiya-Oba
